blesser.....If you quarantined new fish before adding to your main tank, you could avoid this problem. I have a little 5 gallon I keep just for this reason. Cost me $8 plus a cheapie filter. So much easier than having this problem a couple weeks down the road.

Ok so removing all the fishs and leaving the shrimps alone in the main tank can solve the problem. Im thinking get a 10 gallons to put all my fish in for 1 month and leave the main tank with the shrimps in , so the ick supose to die due to no host if im rite =)
